CT、MRI在小儿病毒性脑炎诊断中的效果分析

Comparison of the effects of CT and MRI in the diagnosis of viral encephalitis in children

目的分析CT和MRI在小儿病毒性脑炎的临床诊断价值。方法选择2015年11月~2017年2月我院接诊经脑脊液常规检查后确诊的47例病毒性脑炎患儿为研究对象,将患儿的CT检查和MRI检查结果进行比较,分析两种检查方法的敏感性及其诊断价值。结果 CT检查显示,47例患儿中,37例患儿的检查结果为阳性,阳性检出率为78.72%;MRI检查显示,47例患儿中,44例检查结果呈阳性,阳性检出率为93.62%。两种检查方法的阳性检出率比较,差异有显著统计学意义(P<0.05);其中CT检出多发病灶29例,占比61.70%;MRI检出多发病灶33例,占比70.21%。MRI检查的诊断率明显高于CT检查,差异有统计学意义(P<0.05)。结论 MRI对小儿病毒性脑炎的阳性检出率较高,多发病灶的检出效果更好,相比于CT检查具有较高的诊断价值,值得推广。

Objective To compare the clinical value of CT and MRI in the clinical diagnosis of viral encephalitis in children. Methods In this study,47 children with viral encephalitis were enrolled in our hospital.The cases were selected from November 2015 to February 2017.All the children were diagnosed by routine examination of cerebrospinal fluid.All the children were examined by CT and MRI.The results of the two methods were compared with the pathological results after operation.The sensitivity of the two methods was calculated and the diagnostic value of the two methods was analyzedt. Results CT showed that in 47 cases,37 cases of test results were positive,the positive rate was 78.72%,MRI showed that in 47 cases,44 cases of the test results are positive,the positive rate was 93.62%,two methods of positive rate comparison,the difference is distinct statistical significance(P<0.05);Among them,CT examination detected multiple lesions in 29 cases,accounting for 61.70%,MRI examination detected multiple lesions in 33 cases,accounting for 70.21%,and the diagnostic rate of MRI examination was higher than that of CT examination. Conclusion The diagnosis of children viral encephalitis by MRI examination is more positive,and the detection effect of multiple lesions is better.Compared with CT examination,it has higher diagnostic value and is worth popularizing.
